Reporter cell lines based on human pluripotent stem cells (hPSCs) are highly desirable for studying differentiation, lineage tracing, and target cell selection. However, several technical bottlenecks, such as DNA transduction, low homology recombination rate (HDR), and single-cell cloning, have made this effort an arduous process in hPSCs. Here, we provide a step-by-step protocol and practical guide for generating reporter lines in hPSCs via CRISPR/Cas9-mediated HDR. We also elaborate on the…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
